Well, for one thing, they ensure that a scientist can't claim a certain result, which might be biased and thus inaccurate, because he or she is being paid by, say, big business interests. For another, they ensure that medicines or treatments can't be made available to the public without thorough testing, replication, and peer review.
The pH of the buffer solution : 2.433
<h3>Further explanation
</h3>
A buffer solution is a solution that can maintain a good pH value due to the addition of a little acid or a little base or dilution.
The buffer solution can be acidic or basic
Acid buffer solution consists of weak acids (H₃PO₄) and their salts(NaH₂PO₄)
valence according to the amount of salt anion
[H₃PO₄]=0.00650 M
[NaH₂PO₄]=0.0125 M
Answer:
pH = 0.32
Explanation:
To solve this problem we use the <em>Henderson-Hasselbach equation</em>:
- pH = pKa + log
In this case
- [A⁻] is [NH₃], as it is the conjugate base of a weak acid
- [HA] is [NH₄⁺], as it is a weak acid
So now we just <u>compute the data in the equation</u>
- pH = 9.24 + log
